Abstract: PURPOSE:To enable continuation of stable combustion by reducing to minimum a fluctuation in the flow rate of fuel, fed to a fuel feed electromagnetic valve, which is caused due to a fluctuation in the pressure of a fuel pump and a change in the temperature of oil, by a method wherein, between a forced feeding device and a control valve, a first relief flow passage is communicated with the forced feeding device side of a forced feed passage, and a second relief low pasage is communicated with the control valve side. CONSTITUTION:Between a forced feeding device 4 and a control valve 3, a first relief flow passage, having a first relief valve 5, is communicated with the forced feeding device 4 side of a forced feed passage, and a second relief flow passage, having a second relief valve 7, is communicated with the control valve 3 side to decrease flow resistance of the first relief and increase flow resistance of the second relief. In case there is a fluctuation in the forced feed amount of the forced feeding device 4, the first relief valve 5, having low resistance, can be operated sensitively to a fluctuation in a forced feed amount to relieve an amount equivalent to a fluctuation in the forced feed amount. When the temperature of liquid in a forced feed passage is fluctuated, flow resistance of liquid passing through the control valve 3 is fluctuated, but flow resistance of the second relief valve 7 is fluctuated in a direction in which the fluctuation in the flow resistance is corrected.

IPC: G11B7/085
Filed: 1985-05-20
Abstract: PURPOSE:To access a disc accurately at a high speed by measuring preliminarily track positions and rotation numbers in them with respect to several absolute positions sampled in the overall area of the disc and accessing the disc hereafter in accordance with calculation based on these measured values. CONSTITUTION:The rotation number detected by a disc motor rotation number detector 3 and that from a disc motor rotation number calculating circuit 5 are compared with each other by a comparator 6, and the comparison result is sent to a system control circuit 14. An information reader 7 is so moved that the number of traversed tracks which is calculated by a traversed track number calculating circuit 12 coincides with the number of actually traversed tracks which is detected by a track traverse detecting circuit 10. A current position reading circuit 13 detects the current position in accordance with read information and sends the result to the system controlling circuit 14. Thus,the track position and the disc rotation number are calculated accurately even if the recording linear speed or the track pitch are different by discs or are varied in the same disc, and high-speed random access is possible.

IPC: A61M25/00
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To easily and inexpensively produce a surgical tube having a soft front end. SOLUTION: The dural surgical catheter 1 having the soft distal end 2 is formed by co-extrusion molding of an inner layer 11 and an outer layer 12. The inner layer is molded of plastic softer than the outer layer. An extruder 20 has two extrusion heads. The extrusion head for the inner layer 11 has a mobile cone and periodically moves this mobile cone to increase the bore of the inner layer, then to completely shut off the flow of the extrudate. As a result, regions 13 having portions 14 where the inner layer 11 is made thin and portions 15 where there is no inner layer are formed. A tubular molding is cut at the ends of these regions 13 and thereafter the ends are closed to form lateral openings 3, by which the patient side distal end 2 is provided with the rigidity lower than the rigidity of the remaining part of the catheter 1.

Title: Receiving circuit of differential signal
Inventor: MIZOHATA FUMIO
IPC: H04L25/02
Filed: 1981-07-08
Abstract: PURPOSE:To actuate the signal state to the safety side and to prevent the malfunction, by making a differential comparator inactive mode when the outputs of two transistors are at a low or high level respectively. CONSTITUTION:When the output B and C are at a high level respectively, the resistance circuits 9 and 12 set these outputs at a slightly low level respectively. Thus an output signal F is set at a low level and inactive. While in case the outputs B and C are set at low levels, the resistance circuits 8 and 11 set these outputs at a slightly high levels, then the signal F is being kept inactive. When the outputs B and C are coincident with each other, it is clear that the transistors 6 and 7 are in faulty-state, according, the sinal F is made inactive, and the signal state is actuated to the safety side. As a result, the malfunction is avoided.

Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To obtain an OFDM receiver which efficiently attains frequency deinterleaving with respect to hardware. SOLUTION: In an OFDM receiver, an input section INS reconstitutes a received OFDM transmission signal RF to a digital signal IQ. A demodulator input buffer DIB converts the digital signal IQ from the input section INS into a burst-like signal ID and supplies the signals ID to a fast speed Fourier transform type demodulator DEM. In response to the signal ID, the demodulator DEM generates a burst-like output signal DB. Each burst MB (.) in the output signal DB includes demodulation samples me (.) related to carriers F (1),..., F(N) in the signal RF. In each burst MB (.), the demodulation samples me (.) are written in a demodulator output buffer DOB. Before the start of a succeeding burst MB (.), these demodulation samples me (.) are read out in an order which is different from the order in the burst MB (.). Consequently frequency deinterleaving, in particular, is attained.

Title: Magnetic separating filter
Inventor: YANO JIYUNICHI
IPC: B01D35/06
Filed: 1977-09-06
Abstract: PURPOSE:To greatly increase the quantity of attracted magnetic particles per unit area of filter elements, by making the numerous filter elements of ferrite-austenite steel and increasing the number of magnetic modules of each magnetic element. CONSTITUTION:A cylindrical filter container 3 is made of non-magnetic material (e.g., aluminium) so that a fluid introduced through an inlet port 4 is conducted to an outlet port 6 through a filtering portion 5. Since the ferromagnetic austenite structure of each of the filter elements 10 filled in the filtering portion 5 is very fine one at micron order, the fine magnetic modules are magnetized and a very high magnetic field gradient is produced when magnetic field is applied to the filter elements. Therefore, the effective area for attraction of magnetic particles can be made very large. The magnetic particles contained in the fluid introduced throgh the inlet port 4 are attracted to the magnetic modules. Then, the fluid is drained through the outlet port 6.
